NCI performed survey and relief sewer design services as a subconsultant for Tetra Tech to eliminate the sanitary sewer overflow (SSO) as a part of Phase 2 of this dual phased project. In addition, NCI provided the full topographic survey and right-of-way resolution for Phase 1 of this project which included the installation of nearly 3,000 feet of 24” force main to a 3.0 MG underground storage facility.

To initiate the project, NCI conducted the complete field survey and right-of-way resolution for the project corridor and storage basin site. Once the survey was processed and the base maps created, preliminary routing and locations were evaluated and determined. Based on the preliminary engineering, it was determined 5,600 feet of sewer varying in size from 18” to 36” was required to provide the necessary amount of relief.
